I have been facing exactly the same problem. I'm also on a VPS (VPSLatch), and have vBulletin + vBSEO. Today the server load reached upto 50+ (which normally stays around 0.5 - 1). I disabled all the Plug-ins GLOBALLY, However, the problem still persists. The VPS Management staff is still telling that vBSEO is the cause but howcome when all my plugins are globally disabled? I use around seven plug ins anyway. After this today's issue, I have strong feeling that vBSEO is NOT the ultimate cause. Also, It's important to note that I have been on the same VPS server since about a year and not faced much of problems so howcome all of sudden, when even traffic has marginal increase? I would like to hear some comments from REAL experts here.

PS: Another thing to note is that memory usage always stays under control. It's mainly CPU load which drastically shoots up. So upgrading the RAM won't help either.

Maybe the node is overloaded causing high disk IO/abusive users, etc. Could be DDoS attacks. It could be anything. Only HostDime/VPSLatch will know the real reason. If you don't believe them, you can try another host that offers a 30 Day Money Back guarantee to test it on a different setup.

If you have not updated your scripts ( VB + Plugins : a new version could bring in some bugs etc ) + no traffic increase + when you disable the plugins the cpu load remains high...then my opinion is that there is another guy ( VPS ) or tasks on the main node that create issues or even a software/hardware issue on the main node itself. I'm not a "real" expert...just my opinion.

you said it well.in this case i never recommend vbseo with VPS.perhaps with dedicated yes it will be fine.this is kind of major issue.even vbseo staff not ready to help any more with this issue.memory is 1GB but still nothing any issue with the memo.but we tried with 5 cpu added but still remain the same issue.any experts here please give us some advice thanks.

we have changed the node as well but same issue.I don't think it is DDos but all problem with VBSEO.They are not giving proper answer to optimized the server.as a paid product pissed me off.
